Pain as a reason for primary care visits: Cross-sectional survey in a rural and periurban health clinic in the Eastern Cape, South Africa

Background: The burden of pain in primary care has not been described for South Africa. This study aimed to determine the prevalence of pain in primary care and to characterise pain among adult patients attending a rural and a periurban clinic in the Eastern Cape (EC) Province.Method: A cross-sectional descriptive survey was conducted among adult patients attending a rural and periurban clinic over four days. Consecutive patients were asked whether they were in the clinic because of pain and whether the pain was the major reason for their visit. Pain was characterised using an adaptation of the Brief Pain Inventory and the Pain Disability Index. The prevalence percentage and the 95% confidence interval (CI) of pain were estimated, and the relationship with demographic variables was determined at a significance level of P < 0.05.Results: Seven hundred and ninety-six adult patients were interviewed, representing a response rate of 97.4%. Almost three-quarters (74.6%; 95% CI: 63.2-81.4%) reported visiting the clinic because of pain. Pain was the primary reason for 393 (49.4%; 95% CI: 32.1-61.0%) visits and was secondary in 201 (25.3%; 95% CI: 12.8-33.7%) visits. The commonsites of pain were the head, back and chest. The median pain score was eight on a scale of 0-10 (interquartile range: 6-8). Respondents experienced limitations in a number of activities of daily living as a result of pain.Conclusion: Pain is a central problem in public primary care settings in the EC Province and must therefore be a priority area for primary care research. Strategies are needed to develop to improve pain management at primary care level in the province

Chronic pain in the community: a survey in a township in Mthatha, Eastern Cape, South Africa

Background: Comprehensive information is needed on the epidemiology and burden of chronic pain in the population for the development of appropriate health interventions. This study aimed to determine the prevalence, severity, risk indicators and responses of chronic pain among adults in Ngangelizwe, Mthatha, South Africa.Method: A cross-sectional survey utilising structured interviews of a sample of adult residents was used. Interviews elicited information on socio-demographic characteristics, general health status, and the prevalence, duration, frequency, severity, activity limitation and impact of chronic pain.Results: More than 95% (n = 473) of the sampled adults participated in the study. Of these, 182 [38.5%, 95% confidence interval (CI): 36.3-42.5%] reported chronic pain in at least one anatomical site. The most common pain sites were the back and head. The median pain score was 5 on a scale of 0 to 10 [interquartile range (IQR) = 4-7] and the median number of sites of pain was 1 (IQR = 1-2). Female gender [odds ratio (OR) = 2.6, 95% CI: 1.7-3.9] and being older than 50 years of age (OR = 3.5, 95% CI: 2.6-4.1) were identified as risk indicators for chronic pain in the sample. Over 65% of respondents reported that they self-treated; 92.1% had consulted with a doctor or nurse, 13.6% consulted a traditional healer, and 34.5% consulted a pharmacist because of their pain. Despite this, over 50% reported that relief of their pain was transient.Conclusion: Chronic pain is a common general complaint in this community, but there is a need for focused attention on women and the elderly.Keywords: chronic pain, community-based survey, epidemiology, Mthatha, Eastern Cape, South Afric

Non-communicable diseases in antiretroviral therapy recipients in Kagera Tanzania: A cross-sectional study

Introduction: The aim of this study was to describe the extent of  self-reported non-communicable diseases (NCDs) among highly activeantiretroviral therapy (HAART) recipients in Kagera region in Tanzania and their effect on health-related quality of life (HRQOL). This study was conducted 2 years after HAART administration was started in Kagera region. Methods: The SF-36 questionnaire was used to collect the HRQOLdata of 329 HAART recipients. Questions on the NCDs, socio-demographic characteristics and treatment information were validated and added tothe SF-36. Bivariate analyses involving socio-demographic characteristics and SF-36 scores of the recipients were performed. Multiple logisticregression was employed to compute adjusted odds ratios for different explanatory variables on physical functioning and mental health scores.Results: Respondents who reported having 1 or more NCDs were 57.8% of all the respondents. Arthritis was the commonest NCD (57.8%).Respondents with the NCDs were more likely to have HRQOL scores below the mean of the general Tanzanian population. The populationattributable fraction (PAF) for the NCDs on physical functioning was 0.28 and on mental health was 0.22. Conclusion: Self-reported NCDs were prevalent among the HAART recipients in Kagera region. They accounted for 28% of the physical  functioning scores and 22% of the mental health scores that were below the mean of the general Tanzanian population. Therefore, the integration of NCD care is important in the management of HIV/AIDS

Mapping geographical inequalities in oral rehydration therapy coverage in low-income and middle-income countries, 2000-17

Background Oral rehydration solution (ORS) is a form of oral rehydration therapy (ORT) for diarrhoea that has the potential to drastically reduce child mortality; yet, according to UNICEF estimates, less than half of children younger than 5 years with diarrhoea in low-income and middle-income countries (LMICs) received ORS in 2016. A variety of recommended home fluids (RHF) exist as alternative forms of ORT; however, it is unclear whether RHF prevent child mortality. Previous studies have shown considerable variation between countries in ORS and RHF use, but subnational variation is unknown. This study aims to produce high-resolution geospatial estimates of relative and absolute coverage of ORS, RHF, and ORT (use of either ORS or RHF) in LMICs. Methods We used a Bayesian geostatistical model including 15 spatial covariates and data from 385 household surveys across 94 LMICs to estimate annual proportions of children younger than 5 years of age with diarrhoea who received ORS or RHF (or both) on continuous continent-wide surfaces in 2000-17, and aggregated results to policy-relevant administrative units. Additionally, we analysed geographical inequality in coverage across administrative units and estimated the number of diarrhoeal deaths averted by increased coverage over the study period. Uncertainty in the mean coverage estimates was calculated by taking 250 draws from the posterior joint distribution of the model and creating uncertainty intervals (UIs) with the 2 center dot 5th and 97 center dot 5th percentiles of those 250 draws. Findings While ORS use among children with diarrhoea increased in some countries from 2000 to 2017, coverage remained below 50% in the majority (62 center dot 6%; 12 417 of 19 823) of second administrative-level units and an estimated 6 519 000 children (95% UI 5 254 000-7 733 000) with diarrhoea were not treated with any form of ORT in 2017. Increases in ORS use corresponded with declines in RHF in many locations, resulting in relatively constant overall ORT coverage from 2000 to 2017. Although ORS was uniformly distributed subnationally in some countries, within-country geographical inequalities persisted in others; 11 countries had at least a 50% difference in one of their units compared with the country mean. Increases in ORS use over time were correlated with declines in RHF use and in diarrhoeal mortality in many locations, and an estimated 52 230 diarrhoeal deaths (36 910-68 860) were averted by scaling up of ORS coverage between 2000 and 2017. Finally, we identified key subnational areas in Colombia, Nigeria, and Sudan as examples of where diarrhoeal mortality remains higher than average, while ORS coverage remains lower than average. Interpretation To our knowledge, this study is the first to produce and map subnational estimates of ORS, RHF, and ORT coverage and attributable child diarrhoeal deaths across LMICs from 2000 to 2017, allowing for tracking progress over time. Our novel results, combined with detailed subnational estimates of diarrhoeal morbidity and mortality, can support subnational needs assessments aimed at furthering policy makers' understanding of within-country disparities. Over 50 years after the discovery that led to this simple, cheap, and life-saving therapy, large gains in reducing mortality could still be made by reducing geographical inequalities in ORS coverage.

Occupational Injuries Among Physiotherapists: A Case Study in Zimbabwe

The purpose of this study was to investigate the prevalence, severity, risks, occupational safety and responses of physiotherapists to work-related musculoskeletal disorders (WMSDs). The subjects for this study were physiotherapists registered with the Medical Rehabilitation Council of Zimbabwe. A total of 198 questionnaires were mailed to physiotherapists in different hospitals and practices in Zimbabwe in the form of a 6-page protocol. Musculoskeletal symptoms in all body areas, physiotherapy speciality areas and tasks, job-related risk factors, preventive strategies adopted (if any) and responses of physiotherapists to WMSDs were investigated. Seventy-eight percent (78%) of physiotherapists reported experiencing WMSDs. The highest prevalence of symptoms was reported in the low back (52.1%), upper back (34.6%) and thumbs (32.5%). One in four physiotherapists took sick leave or required treatment because of WMSDs. Younger physiotherapists reported higher prevalence of symptoms in the upper back, thumb, wrists, hands and neck. The job factor rated most likely to contribute to WMSDs was lifting or transferring dependent patients. The study highlights that knowledge of ergonomics, injury and treatment does not offer the physiotherapist immunity from injury and that occupational safety among physiotherapists should be further investigated.

Availability and affordability of blood pressure-lowering medicines and the effect on blood pressure control in high-income, middle-income, and low-income countries: an analysis of the PURE study data

Background Hypertension is considered the most important risk factor for cardiovascular diseases, but its control is poor worldwide. We aimed to assess the availability and affordability of blood pressure-lowering medicines, and the association with use of these medicines and blood pressure control in countries at varying levels of economic development. Methods We analysed the availability, costs, and affordability of blood pressure-lowering medicines with data recorded from 626 communities in 20 countries participating in the Prospective Urban Rural Epidemiological (PURE) study. Medicines were considered available if they were present in the local pharmacy when surveyed, and affordable if their combined cost was less than 20% of the households' capacity to pay. We related information about availability and affordability to use of these medicines and blood pressure control with multilevel mixed-effects logistic regression models, and compared results for high-income, upper-middle-income, lower-middle-income, and low-income countries. Data for India are presented separately because it has a large generic pharmaceutical industry and a higher availability of medicines than other countries at the same economic level. Findings The availability of two or more classes of blood pressure-lowering drugs was lower in low-income and middle-income countries (except for India) than in high-income countries. The proportion of communities with four drug classes available was 94% in high-income countries (108 of 115 communities), 76% in India (68 of 90), 71% in upper-middle-income countries (90 of 126), 47% in lower-middle-income countries (107 of 227), and 13% in low-income countries (nine of 68). The proportion of households unable to afford two blood pressure-lowering medicines was 31% in low-income countries (1069 of 3479 households), 9% in middle-income countries (5602 of 65 471), and less than 1% in high-income countries (44 of 10 880). Participants with known hypertension in communities that had all four drug classes available were more likely to use at least one blood pressure-lowering medicine (adjusted odds ratio [OR] 2·23, 95% CI 1·59–3·12); p<0·0001), combination therapy (1·53, 1·13–2·07; p=0·054), and have their blood pressure controlled (2·06, 1·69–2·50; p<0·0001) than were those in communities where blood pressure-lowering medicines were not available. Participants with known hypertension from households able to afford four blood pressure-lowering drug classes were more likely to use at least one blood pressure-lowering medicine (adjusted OR 1·42, 95% CI 1·25–1·62; p<0·0001), combination therapy (1·26, 1·08–1·47; p=0·0038), and have their blood pressure controlled (1·13, 1·00–1·28; p=0·0562) than were those unable to afford the medicines. Interpretation A large proportion of communities in low-income and middle-income countries do not have access to more than one blood pressure-lowering medicine and, when available, they are often not affordable. These factors are associated with poor blood pressure control. Ensuring access to affordable blood pressure-lowering medicines is essential for control of hypertension in low-income and middle-income countries.
